Protein defence systems against the lantibiotic nisin: Function of the immunity protein NisI and the resistance protein NSR

Frontiers in Microbiology, 2016
Lantibiotics are potential alternatives to antibiotics because of their broad-range killing spectrum. The producer strain is immune against its own synthesized lantibiotic via the expression of two proteins LanI and LanFEG.

The Effectiveness of Postharvest Processing on Microbiological Safety of Game Meat—A Systematic Review

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 2, March 2026.
ABSTRACT The rising global consumption of game meat has highlighted gaps in the management of biological hazards associated with its production and consumption, and the safety of processed game meat products remain insufficiently addressed. Therefore, there is a need for research evaluating the effectiveness of processing and preservation methods in ...

Plasma mutation breeding of Lactococcus lactis in producing Nisin

Journal of Hebei University of Science and Technology, 2015
With Nisin-producing Lactococcus lactis as the starting strain, the strain with tolerance to 10 000 IU/mL Nisin is selected on high-concentration Nisin medium. The Nisin titer of the strain is up to 1 680 IU/mL.

Binding of Bacillus subtilis dynamin‐like protein DynA to the bacterial membrane is essential for effective phage defense

The FEBS Journal, Volume 293, Issue 6, Page 1741-1753, March 2026.
The bacterial dynamin‐like protein DynA from Bacillus subtilis plays a key role in phage defense. It binds the plasma membrane through a unique paddle domain in its D1 subunit. This membrane association is essential for its protective function, likely preventing explosive membrane rupture following phage infection.

Plant Proteins as Emulsifiers in the Food Industry: Research Progress, Current Challenges and Future Trends

Journal of the American Oil Chemists' Society, Volume 103, Issue 2, Page 99-121, February 2026.
ABSTRACT The impressive growth in the global market for plant‐based foods has a direct impact on the food industry, requiring greater efforts in product reformulation for the replacement of animal‐based ingredients, including proteins. The replacement of animal‐derived proteins frequently applied as emulsifiers in food formulations, for example ...

Natural approach of using nisin and its nanoform as food bio-preservatives against methicillin resistant Staphylococcus aureus and E.coli O157:H7 in yoghurt

BMC Veterinary Research
Background Natural antimicrobial agents such as nisin were used to control the growth of foodborne pathogens in dairy products. The current study aimed to examine the inhibitory effect of pure nisin and nisin nanoparticles (nisin NPs) against methicillin

Emergence of Staphylococcus aureus Resistance to Antimicrobial Peptides Nisin, NZ2114 and Bacitracin Involves Multiple Phenotypic Changes

Animal Research and One Health, Volume 4, Issue 1, Page 82-93, February 2026.
The AMP‐induced mutant Staphylococcus aureus strain nzR showed increased resistance, five gene mutations, and decreased surface anion levels. AMPs affect the NDH‐2 protein encoded by ndh gene inhibiting the growth of S. aureus. The deletion of the ndh gene promotes the development of AMPs resistance.

Polyphasic Validation of a Nisin-Biogel to Control Canine Periodontal Disease

Antibiotics, 2020
Background: Periodontal disease (PD) is a highly prevalent inflammatory disease in dogs. This disease is initiated by a polymicrobial biofilm on the teeth surface, whose control includes its prevention and removal.

Mutagenesis of nisin’s leader peptide proline strongly modulates export of precursor nisin

Antonie van Leeuwenhoek, 2016
The lantibiotic nisin is produced by Lactococcus lactis as a precursor peptide comprising a 23 amino acid leader peptide and a 34 amino acid post-translationally modifiable core peptide. We previously demonstrated that the conserved FNLD part of the leader is essential for intracellular enzyme-catalyzed introduction of lanthionines in the core peptide ...
